电子邮件内容具有我自己的域名时，电子邮件不起作用

I am using simple php script for sending a mail , when I use my own domain name as email content like this

$message="Please visit us at https://myhouseinthecloud.com/";
mail($email,$subject,$message,"From: $from
");

then my email stops working and if I remove this link,as

 $message="Please visit us";
 mail($email,$subject,$message,"From: $from
");

then it works. I didn't get what is the problem. I h've problem only with this domain.

Please try using a anchor tag like <a href='https://myhouseinthecloud.com/'>Click Here</a> for more info: http://www.webhostingtalk.com/showthread.php?t=416467
